* Finish moving of dig(1) to /usr/bin/dig by removing the sources in theflorian2020-02-119-9523/+0
| | | | | old location. dig(1) sources can be found in src/usr.bin/dig. ok deraadt@
* Replace atoi with strtonum for stricter and safer integer parsing.florian2020-02-051-9/+15
| | | | | | | | | | | | | | | | -N ndots: 0, INT_MAX The upper limit is a bit silly, everything bigger than a small number will force domain names to be interpretet as relative. -R retries INT_MIN, INT_MAX - 1 Specifically documented to accept negative numbers. -W wait 0, INT_MAX One could interpret the documentation as meaning that it accepts negative numbers but that failes later on with an error message from the timer code.. with deraadt, OK kn, input & OK tedu
* just use netdb.h directlyflorian2020-02-041-14/+7

* Remove unused typedefs that got left behind in previousflorian2020-02-041-4/+2
| | | | | | | | shreddings from types.h and get rid of offset.h while here by just using off_t in the one place where it's needed. However offset.h brought in limits.h and sys/types.h so sprinkle some includes over the tree to have various _MAX and intX_t defined.
* Get rid of getopt(3) compat code.florian2020-02-042-31/+28

* Nuke autohell from orbit. It's the only way to be sure.florian2020-01-281-111/+0
| | | | OK sthen
* Switch to Makefile based builds.florian2020-01-286-13/+28
| | | | | | | | Delete a bunch of files that were no longer built but still lying around. Since there are no subdirectories below obj any more we need to prefix dns/{log,time,result}.c with dns_ to not conflict with the same names used by lib/isc/. OK sthen
* Support for queries on ports != 53jca2020-01-263-5/+5
| | | | | | | | | | | | | | - dig(1) -p now works, as already supported by dig(1) from ports/net/isc-bind thanks to sthen@ - "set port=..." also works in nslookup(1) - host(1) has no support for alternate destination ports This adds "inet" to the pledge promises of all three programs, a compromise deemed reasonable and suggested by deraadt@; instead of slightly more complicated patches by myself and florian@ to avoid "inet" in the general case. Suggested by deraadt@, ok florian@ sthen@
* Remove now unused unix/file.c and unix/fsaccess.cflorian2020-01-261-2/+2
| | | | OK jca, tedu
* unifdef sigchase. It is deprecated and never enabled on openbsd.florian2020-01-255-2381/+2

* The config parser lets us know when the key file can't be found.florian2020-01-251-4/+1
| | | | Not need to check beforehand and enter a race.
* Since we are no longer using config.h we can remove a lot of featureflorian2020-01-241-9/+7
| | | | | | | | | checks from configure. Work started by tedu, I tossed a bunch more. "go ahead" tedu This is not comprehensive but returns where diminishing in terms of saved build time. The next step would probably be to remove configure entirely.
* We can always create IPv4 and IPv6 sockets.florian2020-01-231-13/+3
| | | | | While here cleanup net.h. OK deraadt
* config.h and platform.h are unused nowflorian2020-01-224-7/+7

* unifdef the last config.h bitsflorian2020-01-222-5/+1
| | | | OK millert
* remove mutex.h etc. since this code is now unthreaded.tedu2020-01-211-55/+1

* We no longer support "memory usage" debugging.florian2020-01-201-5/+3

* Rip out custom memory allocator.florian2020-01-205-160/+110
| | | | OK otto
* As millert@ points out we can replace isc_string_touint64 withflorian2020-01-204-6/+6
| | | | | strtoull(3) and then get rid of lib/isc/string.c OK millert
* Fix a address family desynchronisation between lwres_conf andflorian2020-01-201-2/+8
| | | | | | | | | | | | | | | | | | | | | | dig_serverlist. In one of the first shredding commits lwres unintentionally lost the ability to track if the user requested IPv4 only or IPv6 only operations. Parsing of /etc/resolv.conf would add all nameservers, ignoring their address family. When dig(1) later populated server_list it would pay attention to the address family. If /etc/resolv.conf contains only IPv4 nameservers and it has 3 or more and the user requests IPv6 only operations dig would fail with "add_nameserver failed". This happens because lwres_conf already contains 3 nameservers but server_list is empty so dig tries to add ::1 to lwres_conf. It feels like this is very convoluted but it restores previous behavoir the way it was implemented before. Thus sidestepping some refactoring. OK millert
* Reduce tsig support to what is needed by dig et al by removing theflorian2020-01-201-4/+4
| | | | | | server side support and keyrings. This allows us to get rid of a red-black-tree implementation. OK millert
* Handle documentation of the remaining, more complicated defaultsschwarze2020-01-102-32/+32
| | | | | | | | | | | of query options: * Add some missing information and improve some wordings. * List the supported opcodes. * Mention that +nosubnet is valid. * Stop documenting the confusing +noednsflags because it does the same as +ednsflags. Using feedback from florian@ and wording help from jmc@; OK jmc@.
* Remove readline support from nslookup.florian2020-01-091-26/+0
| | | | OK millert, deraadt
* Use normal int types like int32_t instead of isc_int32_t.florian2020-01-095-54/+54

* We only need the config parser from liblwres.florian2020-01-061-33/+8
| | | | | | | | | | | | This pulls out the config object (lwres_conf_t) from the context (lwres_context_t), switches to libc functions (lwres_net_ntop vs inet_ntop etc ) and removes a lwres_ prefix from number types (lwres_uint8_t vs uint8_t etc). With that we can nearly empty out lib/lwres and lose about 20k lines in the process. OK sthen
* document the defaults for several query options;schwarze2020-01-061-15/+13
| | | | OK jmc@
* Jason suggested that stating defaults with a postfix "(on/off by default)"schwarze2020-01-041-74/+32
| | | | | | is as clear, more concise, and reads better. In a few cases, it also allows shortening text that said the same twice. Tweak and OK jmc@.

* Correct the markup of option arguments involving = signs.schwarze2020-01-021-9/+10
| | | | | | Mostly, move the equal sign out of .Cm and .Ar because we consider it punctuation. Besides, use .Cm rather than .Ar for keywords like "ixfr" and do not mark up literal integer numbers with .Ar.
